Technical Documentation PRODUCT OVERVIEW
The DA-45HR is the world's first 24 bit DAT recorder, providing a cost effective high resolution mastering solution. The DA-45HR can also operate in a standard 16 bit DAT resolution, providing seamless backwards compatibility with other DAT recorders. A full audio I/O complement and word sync in/thru provide all the tools to integrate into any analog or digital studio of any size. Perfect for studios and mastering houses, the DA-45HR bridges the gap between the 16 bit and 24 bit worlds with a familiar interface you already know.

APPLICATIONS

The DA-45HR combines offers all the advantages of a studio grade DAT recorder, and adds the additional capabilities of 24 bit high resolution audio. Project Studio - Production Studio While 16 bit is still the common delivery method in the consumer channel, mass distribution at 24 bit resolution is being promised in the near future. Mixing your projects down on 24 bit masters now will help you capitalize on higher resolution re-releases down the road without having to go back to the studio to remix the tracks. In fact, a number of mix engineers have specified the 24 bit DAT format as their delivery method, and many mastering houses are equipped with DA-45HRs to accept the 24 bit maters. With the proliferation of high resolution multitrack recorders like the DA-78HR and DA-98HR and 24 bit digital audio workstations, the need for high resolution mastering recorders is all the more obvious. Since DATs are already standardized as the method of delivery in studios everywhere, the ability for the DA-45HR to double as a standard 16 bit DAT with total backwards compatibility offers a cost effective solution to bring the best of both worlds into the studio. For studios that keep the audio totally in the digital domain, the DA-45HR offers AES/EBU and SPDIF coaxial ports, as well as word sync in/thru for locking to external word clock sources. These advanced features will provide all the amenities to integrate into any digital or analog studio of any size. Radio Broadcast - Show Control For broadcast and show control applications, the DA-45HR offers a parallel I/O on the back panel for custom remote control. The DA-45HR offers full compatibility with DAT tapes recorded in long play, standard modes, or 24 bit high resolution. Plus, when creating your sound cues, the DA-45HR is the best sounding, most flexible recordable 24 bit format available. This means you can customize your shows as time goes on, without having to re-press DVDs or some other locked, closed end format.

24 BIT DAT FAQ

How does the 24 bit DAT format work? The 24 bit format DAT uses the same DAT tape that is used in standard DAT recorders. In order to store the extra data generated by higher resolution recording, the tape speed is doubled in HR (High Resolution) mode. So, when you're recording in 24 bit HR mode, a standard 120 minute tape will last 60 minutes. Obviously, 24 bit DAT tapes will only play back on a 24 bit DAT recorder like the DA-45HR. How can I work with other users who don't have a 24 bit DAT? The DA-45HR can also run just like a standard 16 bit DAT recorder, running normal speed and writing 16 bits to the tape. Reading and writing is fully supported, so you won't have to dig out a different DAT recorder for anything else. How can I make duplicates of a 24 bit DAT? This all depends on what you've got in your studio. If you have a 24 bit DAW or multitrack, you can dump tracks back and forth that way, however these devices may not support track IDs, track names, and other subcode data. Obviously, you can use two DA-45HRs to make real time copies to duplicate everything on the tape. The other choice is to use a TASCAM DA-302 dual well DAT recorder. While the DA-302 is not equipped to record or play back 24 bit DAT tapes, it can duplicate them as a straight data transfer between tapes.

HELPFUL FUNCTIONS
Track Names The DA-45HR fully supports program titles, allowing each track to have its own name. This information is stored in the tape's subcode, and does not affect the audio quality or cause conflicts with other machines. The name can be spelled out with upper and lower case letters, numbers, and some basic punctuation. Two Memo Locate Points When working on mixes, or even running live shows, a pair of memo points comes in handy. These are separate locate points that can be used for cueing the tape to a particular location, or they can be used for looping a part for rehearsal or critical listening passes. Single Play If you are using the DA-45HR in a live production, the single play function allows you to play the DAT one track at a time. The DA-45HR will automatically stop at the next track ID, ready for the next cue. Margin Counter This is one of those features you typically never think about until you don't have it. The margin counter is very useful when performing transfers. You can walk away from the unit, and know if the level ever peaked out, or if the recording could have been made louder. Drum Time (Head Time) Counter For maintenance purposes, it helps to know if it is time to clean the heads. Maintenance records can be kept just like taking the odometer reading on car. Selectable Reference Level, Attenuation on Outputs Most professional gear operates with -20dB as the 0dB analog reference level, and most semi-pro gear operates at -16dB reference level. The DA-45HR offers the ability to properly match your system to the gear you are working with. There are also attenuation pots on the balanced outputs for fine adjustment of these levels.

Technical Documentation PRODUCT OVERVIEW
TASCAM's DA-302 is the world's only dual well DAT recorder. The DA-302 offers all the functionality of two DATs with the ability to make two masters of a single tape, copy from one DAT well to the other, or the ability to play on one DAT while recording the other. However, other functions are available that never existed before (or required lots of extra gear) like 2x DAT dubbing, extended play between both decks, and cascading of multiple DA-302s for duplication or playback. No major studio, dup house or live venue should be without a DA-302.

APPLICATIONS

DAT tapes have been a standard transfer medium in the professional audio industry since the introduction of the format. DAT is the only true non-compressed digital audio format that was intended to be a target writing media. The simple flexibility and worry-free operation of DAT recorders contributed to the initial rise of the format, and continues to support it in all levels of recording. The DAT format also supports deeper levels of recording flexibility. Multiple sample rates can be used, ranging from the long play 32kHz, to the CD standard 44.1kHz, to 48kHz for higher quality. Plus, the DAT tapes are reasonably inexpensive and offer up to 2 hours (4 hours in LP mode) of uninterrupted audio. TASCAM is the leading manufacturer in professional DAT recorders. The DA-302 continues the proud tradition of excellence in studio and production DAT recorders. Studios (Any Level) When you mix down a DAT, how do you make archival or distribution copies? You can either get two DAT recorders, or you can get the DA-302. The fact that the DA-302 offers high speed dubbing also allows you to save valuable time in the production schedule. For higher end users who are using 24 bit DAT or time code DATs, the DA-302 can also duplicate those. (The DA-302 cannot play a 24 bit DAT, but it can duplicate it directly across.) Live Recordings - One Man Show - Logging Functions The DA-302 offers a number of possibilities in extended play applications. If the decks are set to record in cascade from one deck to the other while in long play mode, the two DAT wells will offer 8 hours of unattended recording time. For live recordings, the regular speeds could be used for a live to 2 track mix, or a steady feed from a buss output for back-up functions. In the one man show application, the entertainer could have background tracks playing from one well, and the other well could be recording the whole performance. Or, one DAT could be playing while the other is cued up.
